Abstract

The invention relates to the use of proton pump inhibitors as combination therapeutics in the treatment of bacterial diseases which do not affect the gastrointestinal tract using antibacterially active compounds.

Description

PROTON PUMP INHIBITOR IN THERAPEUTIC COMBINAΗON WITH ANTIBACTERIAL SUBSTANCES
Field of application of the invention
The invention relates to the use of proton pump inhibitors as combination therapeutics in the treatment of bacterial diseases which do not affect the gastrointestinal tract using antibacterially active compounds.
Known technical background
A large number of patent applications and patents describe variously substituted 2-(2- pyridinylmethylsulfinyl)-1 H-benzimidazoles. This class of compound is able to specifically inhibit gastric acid production and is therefore also described as the proton pump inhibitors class. A whole series of proton pump inhibitors are in an advanced stage of clinical testing or already on the market. The following compounds, designated by the INN, which may be mentioned as examples are: omeprazole (EP-B 005 129), pantoprazole (EP-B 166 287), lansoprazole (EP-B 174 726), rabeprazole (EP-B 268 956), leminoprazole (DE-A 35 31 487) and nepaprazole (EP-A 434 999).
European Patent 166 287, in which, inter alia, the compound pantoprazole (INN) is patented, states that the compounds according to the invention are suitable for the prevention and treatment of gastrointestinal diseases, such as can be caused, for example, by microorganisms, bacterial toxins, antiinflamma- tories, antirheumatics, ethanol, gastric acid or stress situations. - European Patent 544 760 describes combinations of pantoprazole with antibacterially active compounds for controlling the bacterium Heli- cobacter pylori, which populates the stomach.
Description of the invention
Surprisingly, it has now been found that, using proton pump inhibitors as combination components, side effects caused by antibacterially active compounds can be avoided.
The invention therefore relates to the use of proton pump inhibitors as combination therapeutics in the treatment of bacterial diseases which do not affect the gastrointestinal tract using antibacterially active compounds. The invention further relates to the use of proton pump inhibitors for the production of medicaments for combined use in the treatment of bacterial diseases which do not affect the gastrointestinal tract using antibacterially active compounds.
The invention likewise relates to the combination of proton pump inhibitors with an antibacterially active substance for use in the treatment of bacterial diseases which do not affect the gastrointestinal tract.
The invention furthermore relates to the use of proton pump inhibitors for avoiding side effects which can be caused by antibacterially active substances.
The following compounds, designated by the INN, may be primarily mentioned as proton pump inhibitors: omeprazole, lansoprazole, rabeprazole, leminoprazole, nepaprazole and in particular pantoprazole. The designation "proton pump inhibitors" is intended to mean both the compounds themselves and also their pharmacologically tolerable salts, in particular the salts with bases. Thus the designation "pantoprazole" additionally includes the pharmacologically tolerable salts of pantoprazole, especially the salts with bases, such as are described in European Patent 166 287, in particular the sodium salt.
Examples which may be mentioned of bacterial diseases which do not affect the gastrointestinal tract are infections of the bones and joints, the soft parts, the skin and mucous membranes, the kidneys and the renal pelvis, the efferent ureters, the sex organs and the CNS, in particular infections of the ENT region and of the respiratory tract, such as, for example, bronchitis or pneumonia.
Antibacterially active compounds which may be mentioned are β-lactam antibiotics, for example penicillins (such as benzylpenicillin, phenoxymethylpenicillin, propicillin, azidocillin, dicloxacillin, flucloxacillin, oxacillin, amoxicillin, bacampicillin, ampicillin, mezlocillin, piperacillin or azlocillin), cephalosporins (such as cefadroxil, cefaclor, cefalexin, cefixim, cefuroxim, cefetamet, cefadroxil, ceftibuten, cefpodoxim, ce- fotetan, cefazolin, cefoperazon, ceftizoxim, cefotaxim, ceftazidim, cefamandol, cefepim, cefoxitin, cefo- dizim, cefsulodin, ceftriaxon, cefotiam or cefmenoxim) or other β-lactam antibiotics (e.g. aztreonam, loracarbef or meropenem); enzyme inhibitors, for example sulbactam, tetracyclines, for example tetra- cycline, oxytetracycline, minocycline or doxycycline; aminoglycosides, for example tobramycin, genta- micin, neomycin, streptomycin, amikacin, netilmicin, paromomycin or spectinomycin; amphenicols, for example chloramphenicol or thiamphenicol; lincomycins and macrolide antibiotics, for example clinda- mycin, lincomycin, erythromycin, clarithromycin, spiramycin, roxithromycin or azithromycin; polypeptide antibiotics, for example colistin, polymixin B, teicoplanin or vancomycin; gyrase inhibitors, for example norfloxacin, cinoxacin, ciprofloxacin, pipemidic acid, enoxacin, nalidixic acid, pefloxacin, fleroxacin or ofloxacin; nitroimidazoles, for example metronidazole; or other antibiotics, for example fosfomycin or fucidic acid, where these antibacterially active substances are administered on their own or alternatively can be combined with one another. Side effects of the antibacterially active substances which may be mentioned, which can be avoided by the administration of proton pump inhibitors, are, in particular, atrophic gastritis.
"Combination therapeutic" or "combination" in the sense of the present invention is thus to be understood as meaning that the individual components (i.e. the proton pump inhibitor on the one hand and the antibacterially active substance or active substances on the other hand) can be administered in a manner which is known and customary per se simultaneously (in the form of a combination medicament), more or less at the same time (from separate pack units) or successively (directly one after the other or else with a relatively large time interval).
In the case of administration of the individual components more or less at the same time from separate pack units and in the case of the administration of the individual components which takes place one after the other, it is possible, if desired, to select a different administration form. For example, one component can be orally administered, while the other component is intravenously administered.
The dosage of the antibacterially active substance(s) is carried out in the customary order of magnitude for the respective substance and the respective purpose, in the case of clarithromycin, for example, with a daily dose of 500 to 1000 mg. In the case of the combined use of a number of.antibacterially active substances simultaneously, if appropriate, a lower dosage of the combination components in each case is carried out.
The proton pump inhibitors are administered in the dose customary for them, but preferably in a lower dosage.
Pantoprazole is administered in the customary daily dose of 40 mg, but preferably in a lower dosage (for example 10 to 20 mg/day). In particular in the case of a lower dosage, the proton pump inhibitors can be administered as combination therapeutics in the prophylactic sense in antibiotic therapy.
Investigation results
In the investigation on dogs described in detail below, it was possible to show that the atrophic gastritis caused by administration of antibacterially active substances can be avoided by the simultaneous administration of proton pump inhibitors: Material and methodology
Animal material 22 dogs (beagles, CPB Harlan, Netherlands)
Age/weight male: 12 months/13.8 kg female: 12.6 months/10.8 kg
Number of animals per group 3m / 3f Experimental period 30 days Recovery time 4 weeks (group 4)
Treatment
Figure imgf000006_0001
The conclusion is drawn from this investigation that proton pump inhibitors, such as, for example, pantoprazole, are able to compensate deep-seated and serious morphological alterations to the mucous membrane, which are obviously caused by antibiotics (in this case the combination clarithromycin and metronidazole). Thus proton pump inhibitors should also be able in antibiotic therapy in man to decrease or to prevent the gastrointestinal side effects caused by the antibiotic.
